I was upset by a call trying to confirm United Airlines reservations for Alice (pronounced A lice) and 20 others who supposedly used my phone number associated with my credit card to make their reservations. I asked to repeat the number and it was my cell phone number. He was startled when I mentioned that I worked for United for 12 years and was unfamiliar with this style of call and his sentence structure was not that of any United employee of any nationality. I am monitoring my credit cards and possible credit for id theft. My home phone line by coincidence was disabled the same week. It all got my attention.
Called travelocity.com to change a reservation; I was told that I would be contacted in 24 hours with a confirmation. The call from the suspicious number was received 12 hours later. The caller stated that they were following up from earlier and that they were calling to request a confirmation of my email address and they also needed me to verify the 3 digit code on the back of my card. Caller was a woman. She mentioned being located in New Delhi, India. I did not provide any information.
Got same call, turned out to be from United Airlines, guy on the other line was clearly Indian and he was able to help me with my ticket refund/exchange.
